The previous `md` breakpoint (768px) caused the desktop layout to activate too early, resulting in a cramped appearance on tablet-sized screens.
This commit updates the responsive design by changing the primary breakpoint from `md` to `lg` (1024px) across the home page, contact page, and main layouts. This change ensures a more appropriate and visually balanced layout is maintained on medium-sized devices, improving the overall user experience.
This commit introduces a major structural refactoring by creating a shared application layout and integrates a toast notification system.
Key changes:
- A new `layout.tsx` file now contains the common Header and Footer components, ensuring a consistent structure across all pages.
- The main `page.tsx` has been simplified to only contain its specific content, with layout elements removed.
- The `react-toastify` library has been added to provide user feedback through toast notifications.
- Custom CSS styles have been applied to the toast notifications for a branded look and feel, including different gradient backgrounds for success, error, warning, and info states.
- The `.gitignore` file was updated to explicitly track the `.env` file, likely for an example configuration.
